I would never waste money to pay for a server. I’ve checked out one someone has. Lag was so bad, I’ve told them I would not get back on till these people fix the lag. And they should get their money back. No one had to pay for bad servers.
Private server or official are both going to be Gportal. I play on 3 Private servers one is mine. They play OK. Perhaps there’s unbridled building and thralls. How many people where on.
